Abstract Generative AI is increasingly used to create texts, including fictional stories. Do stories generated by AI differ from stories created by humans regarding linguistic properties and recipients’ experiences? To answer these questions, we first asked ChatGPT and 100 non-professional human authors (i.e., students) to create stories based on similar prompts (Study 1). Linguistic analyses showed that ChatGPT stories included fewer personal pronouns and fewer descriptions of relativity than human stories, but more positive emotions. In Study 2 ( N = 380), naïve participants were randomly assigned to read an AI-generated or a human story from the pool of 200 stories from Study 1. No differences in novelty or entertainment experiences were found, but the readers of AI stories were less transported into the story world. Mediation analyses show that this difference can be attributed to ChatGPT’s use of fewer personal pronouns. Differences in the use of literary techniques between AI and humans are discussed.
Appel et al. (2025) studied this question.
